💖 BLAS/SRC/zcopy.f 💖

okay bestie, gather round, because today we're talking about BLAS/SRC/zcopy.f — yes she's a Fortran file, yes she's iconic, and yes she is literally the blueprint for copying your complex vector data around. no cap. 🦋

✨ SYNOPSIS ✨

🎀 Functions/Subroutines

  • subroutine zcopy (n, zx, incx, zy, incy) — this is ZCOPY, the whole entire moment 👑

🌸 Function/Subroutine Documentation 🌸

here's the full signature, in all her glory:

subroutine zcopy (integer n, complex*16, dimension(*) zx, integer incx,
    complex*16, dimension(*) zy, integer incy)

ZCOPY 💅

🫶 Purpose:

ZCOPY copies a vector, x, to a vector, y.

that's it. that's the whole job. she copies. she does not overthink. she does not ask questions. main character energy fr fr ✨

🧚 Parameters

  • N — N is INTEGER. it's the number of elements in input vector(s). so like, how many things are we actually copying, bestie.
  • ZX — ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). this is the source vibe, the one we're copying from.
  • INCX — INCX is INTEGER. it's the storage spacing between elements of ZX. lowkey she controls how far apart your ZX girlies are standing.
  • ZY — ZY is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). this is the destination, the one getting the glow-up.
  • INCY — INCY is INTEGER. it's the storage spacing between elements of ZY. same deal as INCX but for the destination side 💜

jack dongarra, linpack, 4/11/78.
modified 12/3/93, array(1) declarations changed to array(*)

so yeah, she's been around since 4/11/78 and got a lil glow-up on 12/3/93 when the array(1) declarations became array(*). aging like fine wine, honestly. 🍓

💀 heads up bestie: this whole page is auto-generated by Doxygen, so if something looks a lil crunchy, that's just the pipeline doing its thing, not a personality flaw.

okay that's the whole tea, ily, go copy your vectors responsibly 🫶
